BACK-BAND BUCKLE.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Application filed June 12, 1918. Serial No. 239,556.

To all whom it may concern:

Be it known that I, LEWELLYN ELKIN, a citizen of the United States, residing at Clarksville, in the county of Montgomery and State of Tennessee, have invented a. new and useful Back-Band Buckle, of which the following is a specification.

It is the object of this invention to provide a simple means whereby the back band of a harness may be connected with a trace carrier, it being possible to adjust the trace carrier longitudinally of the back band, means being provided for holding the trace carrier in ad usted positions longitudinally of the band.

Another object of this invention is to im prove the carrier. I

A further ob'ect of the invention is to rogide novel means for gripping the back an It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes. in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in front elevation, a device constructed in accordance with the invention; Fig. 2 is a section taken approximately on the line 2-2 of Fig. 1, parts being left in elevation; Fig. 3 is a fragni-ental front elevation showing a slightly modified form of the invention; Fig. 4, is a section taken approximately on the line 47% of Fig. 3, distant parts being omitted; Fig.5 is a top plan of the back-plate in that form of the invention which appears in Figs. 3 and 4:, and Fig. 6 is a section taken approxi mately on the line 66 of Fig. 1.

In carrying out the invention as disclosed in Figs. 1 and 2, there is provided a plate 1 equipped at its sides with forwardly presented ears 2 having holes 3. A forwardly extended lip 4 is struck from the plate 1, between the ears 2, and forms a transverse opening 5 in the plate, between the ears. The

plate l'terminates in a reduced neck 6, the extremity of which is fashioned into a resilient hook-shaped latch 7 supplied in its up per edge with a notch 8. Ears 16 are struck forwardly from the plate 1, below the openingi 5.

he numeral 9 marks a cam plate having reduced ends 10 journaled in the holes 3 of the ears 2. The cam plate 9 cooperates with the lip 4 in a way which will be described hereinafter.

The invention comprises a trace carrier 11, including a loop 12 disposed at right angles to the reduced neck 6 of the plate 1, the loop merging into oppositely extended arms 14, terminating in fingers 15 mounted to swing in the ears 16. The loop 12 includes inner and outer bars and a bend connecting the bars, the bend conforming approximately to the concavity of the latch 7 as shown in Fig. 2, and being adapted to be snapped into the latch when the loop is swung toward the plate 1.

The numeral 17 denotes a back band extended along the rear face of the plate 1, the back band being carried forwardly through the opening 5, in contact with the lip 4, it being observed that, as shown in Fig. 2, the lip is curved slightly, so as not to cut the back band. The back band 17 is extended across the forward edge of the cam plate 9 and'is carried rearwardly through the opening 5, the back band thence extending along the rear face of the plate 1, all of which will be clear from Fig. 2. It will be obvious that the cam plate 9, cooperating with the lip 4, serves to hold the back band 17 on the plate 1. It is possible, however, to loosen the loop of the back band which extends across the cam plate 9, and then the plate 1 and parts carried thereby may be adjusted longitudinally of the back band.

A trace (not shown) may be received in the loop 12 of the trace carrier 11, it being possible to swing the trace carrier outwardly with respect to the plate 1, to permit the convenient insertion of the trace into the loop 12. The trace carrier 12 may then be swung inwardly, the end of the loop 12 passing into the notch 8 in the latch 7, the latch 7 gripping the lower end of the loop 12 resiliently, so as to hold the carrier 11 and the trace therein in proper position.

Referring to the modified form of the invention shown in Figs. 3, 1 and 5, there appears a plate 18, corresponding to the plate 1 and having ears'19 provided with perforations as above described. A lip 20 is struck from the plate 18 and forms an opening 21,

the lip 20 corresponding to the lip 4 of F ig.v

l, and the opening 21 corresponding to the opening 5 of .that figure. The plate 18 has a reduced neck 22 on which a trace carrier 23 is mounted in the way described hereinbefore, the trace carrier being supported at 24 for pivotal movement as hereinbefore set forth. One of the parts 2 1 may be proits ends, the rear'p'late 26'i's provided with -torwardlypresented flanges 29 which engage the longitudinal edges of the back band 25 as clearly indicated in Fig. 3. A securing device 30, which may be a bolt, passes through the rear plate 26 the back band 25 and the plate 18,,the securing device being located between the opening 23 and the redu'ced neck .of the plate l8. Securing de vices 31, which may be screws passthrough the rear plate 26 and through the back band 25, the securing devices extending through the opening 21 in the plate'18', The forward ends of the securing devices 31'are' en gaged with retainers which extend across the opening '21,"'the retainers being supplied with hooks 33 engaging the forwardly extendedlip 20.

- It is to be observed thatthe plate 18 and the trace carrier 23 are constructed like the plate 1 and the trace carrier 11, it being possible to use either the cam'plate 9' or the rear plate 26 and the retainers'32.

It is not necessary to rely upon the hold of the latch 7 on the loop 12, in Order to keep the trace carrier 11 in place. Thus one of the ears 16 on the plate 1 may havea finger overhanging one of the arms 14 and provided with an inclined edge 51. WVhen the carrier 11 is swung downwardly into the Copies of t-hispat ent may be obtainedfor arms to the plate to" permit the position shown in Figs. 1 and 2, the arm 14 slides along the inclined edge 51, the corresponding ear 16 yields slightly, and the finger 50 engages in front of the arm 14 as will be clear from the drawings. The construction I above alluded to and described specifically in 1. In a device of the class described','a

front plate having a transverse lip struck therefrom to define an opening; a back'plate cooperating with the front plate; a retainer extended across the opening and engaging thefront plate, the retainer including a hook receiving the lip; a securing device connecting the retainer with the back plate and passing through the opening: and a trace carrier mounted on the front plate.

2. In a device of the class described, a plate provided a't"one'end with aresilient hook-shaped latch; a trace carrier 'compris ing a loop disposedat right angles to the plate and including inner and'outer bars and a bend connecting the bars, the bend being shaped to conform approximately to the concavity of the hook-shaped latch and being'adapted to be snapped there-into when the loop is swung toward and from the plate, the bars being' extended to form laterally projecting arms; and means for pivoting the loop to be swung as aforesaid.

3. In a device of the class described, a plateprovidedwith ears, one ear havinga finger equi ped with an inclined edge; a trace carrier including arms pivoted in the ears, one arm being adapted to ride along the inclined edge and to engage behind the finger to hold the carrier in approximate parallelism with the plate; and means for assembling the plate with a back band.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

LEWELLYN ELKIN.
